New Guinea Impatiens plant named ‘SAKIMP005’

ABSTRACT

A New Guinea  Impatiens  cultivar particularly distinguished by having large, pinkish-red flowers, vigorous rooting, spreading growth habit and variegated leaves is disclosed.

Genus and species: Impatiens×hybrida.

Variety denomination: ‘SAKIMP005’.

BACKGROUND OF THE NEW PLANT

The present invention comprises a new and distinct cultivar of NewGuinea Impatiens, botanically known as Impatiens×hybrida, andhereinafter referred to by the cultivar name ‘SAKIMP005’. ‘SAKIMP005’originated from an interspecific hybridization between ‘NG-02WM1’, anunpatented proprietary deep-orange flowered Impatiens plant and‘NG-01H-15B’, an unpatented proprietary magenta flowered Impatiensplant, in Misato, Japan.

In April 2002, the female parent line ‘NG-02WM1’ and male parent line‘NG-01H-15B’ were crossed and a population of F₁ plants was created. TheF₁ plants were evaluated in Misato, Japan in an open field trial. Thecriteria for plant selection included spreading growth habit, vigorousrooting, pinkish-red flower color and variegated leaves. At thecompletion of the trial, one single-plant selection was made based onthe above criteria and vegetatively propagated. From May to August 2004,the selection was evaluated in an open field in Misato, Japan. Theselection was also evaluated in an open field trial during the summer of2004 in Athens, Ga., USA. Shoot-tip cuttings of the variety were thenshipped in Salinas, Calif., where the plants were regenerated andreevaluated for stability of traits. The selection subsequently wasnamed ‘SAKIMP005’ and found to have its unique characteristics reproducetrue to type in successive generations of asexual propagation. Theinstant plant was asexual reproduced by vegetative cutting in Salinas,Calif.

Plant Breeder's Rights for this cultivar were applied for in Canada onMar. 28, 2007.

SUMMARY OF THE INVENTION

The following are the most outstanding and distinguishingcharacteristics of this new cultivar when grown under normalhorticultural practices in Salinas, Calif.

-   -   1. Pinkish-red flower color;    -   2. Spreading growth habit;    -   3. Vigorous rooting; and    -   4. Variegated leaves.

DETAILED DESCRIPTION OF THE NEW CULTIVAR

The following detailed descriptions set forth the distinctivecharacteristics of ‘SAKIMP005’. The data which define thesecharacteristics were collected from asexual reproductions carried out inSalinas, Calif. The plant history was taken on plants grown for aboutfour months from propagation by terminal cuttings under greenhouseconditions. Color references are primarily to the R.H.S. Colour Chart ofThe Royal Horticultural Society of London (R.H.S.), 4^(th) edition(2001). Anatomic labels are from The Cambridge Illustrated Glossy ofBotanical Terms, by M. Hickey and C.

DETAILED BOTANICAL DESCRIPTION

-   Classification:    -   -   Family.—Balsaminaceae.        -   Botanical.—Impatiens×hybrida.        -   Common name.—Impatiens.-   Parentage:    -   -   Female parent.—‘NG-02WM1’, an unpatented proprietary            deep-orange flowered Impatiens plant.        -   Male parent.—‘NG-01H-15B’, an unpatented proprietary magenta            flowered Impatiens plant.-   Growth:    -   -   Time to produce a rooted cutting.—The terminal 1.0 to 1.5            inches of an actively growing stem was excised. The            vegetative cuttings were propagated in five to six weeks.            The base of the cuttings were dipped for 1 to 2 seconds in a            1:9 solution of Dip 'N Grow (1 solution: 9 water) root            inducing solution immediately prior to sticking into the            cell trays. Cuttings were stuck into plastic cell trays            having 98 cells, and containing a moistened peat moss-based            growing medium. The cuttings were misted with water from            overhead for 10 seconds every 30 minutes until sufficient            roots were formed.        -   Environmental conditions for plant growth.—Rooted cuttings            were transplanted and grown in 6-inch plastic pots in a            glass greenhouse located in Salinas, Calif. Pots contained a            peat moss-based growing medium. Soluble fertilizer            containing 20% nitrogen, 10% phosphorus and 20% potassium            was applied once a day or every other day by overhead            irrigation. Plants were fertilized every 2-3 days, 2 times            in consecutive applications and then given one clear water            application. Pots were top-dressed with a dry, slow release            fertilizer containing 14% nitrogen, 14% phosphorus and 14%            potassium.

‘SAKIMP005’ differs from the male parent, ‘NG-01H-15B’, an unpatentedproprietary Impatiens plant in that ‘SAKIMP005’ has large, pinkish-redflowers, while ‘NG-01H-15B’ has small, magenta flowers. Additionally,‘SAKIMP005’ has a spreading growth habit, while ‘NG-01H-15B’ has amounding growth habit.

‘SAKIMP005’ is similar to the commercial Impatiens variety ‘Misato FG2’(U.S. Plant Pat. No. 17,663) (known commercially as ‘SunPatiens Orange’)however, there are differences as listed in the table below:
